[Tech. Rep. Mode
Shows the states of the I/O ports when the copier is in stand-by.
With the output ports, the change of the data in the port allows an
operation check of electrical components to be performed.
NOTE
For details, see TROUBLESHOOTING.
A sheet of paper is fed through the copier to switch the state of
sensors along the paper path between 1 and 0, thereby determin-
ing whether the sensors are operational or faulty.
<Procedure>
1. Select the paper path (paper source, copying mode, etc.) to be
checked and enter this function.
2. Press the Start key to start the sensor check sequence.
